在传统的用户/服务器网络结构中,本地数据需要传送到目的地去进行计算和处理,而移动代理的出现则使移动计算变为了现实.移动代理的移动性使之比用户/服务器网络结构更适用于传感器网络.本文提出了一种适用于传感器网络的通用移动代理结构.这种结构称为基于移动代理的传感器网络(MAWSN).本结构中的移动代理可以从以下三个方面减少信息冗余度和通信的额外开销以延长网络的生存时间:①通过本地处理功能减少应用层的冗余度;②通过数据汇聚功能减少数据的空间冗余度;③通过多目标数据融合功能减少通信的额外开销.
In the traditional user / server network architecture, local data needs to be sent to the destination for computation and processing, and the advent of mobile agents has made mobile computing a reality. The mobility of mobile agents makes it more user-server networked Which is suitable for sensor networks.This paper proposes a universal mobile agent structure suitable for sensor networks.This kind of structure is called mobile agent based sensor network (MAWSN) .The mobile agent in this structure can reduce the information redundancy from the following three aspects Redundancy and communication overhead to extend the network’s survival time: (1) Reduce the application layer redundancy through local processing capabilities; (2) Through the data aggregation function to reduce the spatial redundancy of data; (3) through the multi-objective data fusion to reduce communication Expenses
